Today’s Patent – Pocket Knife

The said invention (US11999070B1) was invented by Anthony Louis Marfione, and patented by USPTO on October 17^th, 2023. Currently, it stands assigned to the Microtech Knives Inc.

The present invention discloses a pocket knife with improved reliability and reduced manufacturing tolerances. The pocket knife includes a chassis with a cavity, a blade that can be deployed or retracted, a slider, a front operator, a rear operator, and a spring. The slider engages with the front and rear operators to move the blade, and the spring provides the force for deployment and retraction. The invention includes various embodiments with different configurations of the front and rear operators to ensure reliable operation even with reduced manufacturing tolerances.

The invention addresses the challenges of traditional double-action out-the-front pocket knives, which require precise manufacturing tolerances and can suffer from wear and tear over time. By incorporating features such as longitudinal recess or radial flanges, the invention provides a more robust and durable pocket knife that maintains its functionality over repeated cycles.
